ZombiU™ Demo – A great plague has enveloped the city in a fog of death. The Infected prowl through the streets, waiting to prey on your living flesh at every turn. ZombiU is built from the ground up to take full advantage of Wii U, and will test your will to survive in a fear-fueled zombie nightmare. The Wii U GamePad controller becomes your all-in-one survival kit for tools, inventory, med kit and maps. Feel the tension mount as you try to keep your eyes on the TV and Wii U GamePad controller at the same time. ZombiU is available for purchase in the Nintendo eShop on Wii U and at retail stores.
